Sweet Jesus, someone else with a mid 70's Trumpet? My first bike was a 76 Bonne. I spent most of my college time with that bike being my only transportation. I'll never forget riding the 14 miles from school one day in a freezing rainstorm, and when getting home going to wipe the water off my jacket only to have a solid sheet of ice, perfectly moulded to the contours of my leater jacket, open out and drop crashing to the ground.
I've not known of anyone else with a Triumph of that era. Until now.
